A water source block will be created from a flowing block that is next to 2 or more other source blocks, and sitting on top of a solid block or another water source block. This is the rule that makes infinite water sources work. Using this, it is possible to create pools of still water by placing water source blocks in a confined area.

Dispensers loaded with a filled bucket will place a water source block in an empty block in front of them when activated. A dispenser loaded with an empty bucket and a water source just in front of it will suck the source into the bucket when activated.

In snowy biomes, water source blocks have a chance to turn into ice, and reappear when ice melts (except in the Nether). Ice will revert to water when broken if there is a block underneath.

The current in a water block determines both what direction it will appear from its texture to be flowing, and what direction an entity such as a player or boat will float from that block.

The horizontal current in a water block is based on a vector sum of the flows to and from that block from its 4 horizontal neighbors. For example, if a block receives water from the north and sends it both south and east, but borders a solid block on its west edge, then the current in that block will be south-southeast, because 2 southward flows (in and out) are combined with only 1 eastward flow (out). Thus, 16 horizontal directions are possible. If a branch in a channel is 2 blocks wide at its entrance, then entities will float into it rather than continuing in a straight line.

Water with a current pushes mobs at a speed of about 1.39 meters per second, or 25 blocks every 18 seconds.

Players in water take 5 times the normal amount of time to mine blocks while grounded, or 25 times ungrounded. However, with the Aqua Affinity enchantment, mining speed will be faster, which is 1x time grounded, 5x time ungrounded.

Players and mobs (except squid, guardians and iron golems) have a breath meter which lasts 15 seconds, after which they will take damage from drowning while their head is still below water, taking 2 () damage per second until they die.

Each level of Respiration enchantment will add 15 seconds to the maximum time underwater, and will grant an x/(x+1) chance (where x is the Respiration level) of not taking damage after that time: 30 seconds and an average 1 ()/second with Respiration I, 45 seconds and an average of 2⁄3 damage/second with Respiration II, and 60 seconds and an average of 1⁄2 damage/second with Respiration III.

To fill an empty bucket with water, use it on a water source block. The block is consumed in the process. Water buckets can also be filled by smelting a wet sponge in a furnace, with an empty bucket in the fuel slot. The bucket will be filled when the smelting process is complete.

Using a full water bucket on a solid block will place a water source block against that block, emptying the bucket. In the Nether, however, the water will evaporate.

A water bucket will turn into an empty bucket when the player uses it or when a dispenser is activated, letting the water flow out of the bucket.

Water spends most of its time as stationary, rather than 'flowing' – regardless of its level, or whether it contains a current downwards or to the side. When specifically triggered by a block update, water will change to 'flowing', update its level, then change back to stationary. Water springs are generated as flowing, and oceans, lakes and rivers are generated as stationary. This happens before most types of generated structure are created, and the main cause of water "glitches" is that generated structures do not trigger a block update to let water flow into them.

If bit 0x8 is set, this liquid is "falling" and only spreads downward. At this level, the lower bits are essentially ignored, since this block is then at its highest fluid level.

The lower three bits are the fluid block's level. 0x0 is the highest fluid level (not necessarily filling the block - this depends on the neighboring fluid blocks above each upper corner of the block). Data values increase as the fluid level of the block drops: 0x1 is next highest, 0x2 lower, on through 0x7, the lowest fluid level. Along a line on a flat plane, water drops one level per meter from the source.

Height of the water, with 1 being highest.
Also represents the distance from a water source or falling water block.

8–15

Falling water.
This level is equal to 8 plus the level of the non-falling water above it.
For instance a water of level 2 will produce falling water below it with level 10.
The distinction makes no difference in behavior.

Note: The video states that "Infinite water sources are found all over the world in shallower areas." Ever since the 1.5 update, this is no longer the case — water source blocks form even if there isn't a solid block under them, as long as there is a water source block under it, meaning even deep bodies of water can be used as infinite water sources.

Because of the change in how land is generated, if a player is in a world that was made pre-1.8 and travels into new chunks, there's a chance that a very, very large ocean may be formed as the ocean biome. There will also be a one-block-high drop in sea level along the discontinuity between the old and new chunks with the old chunks being higher.

Respiration and Aqua Affinity enchantments added, which allow more breathing time in water and normal digging speed in water.

One-block ceilings of opaque blocks immediately below water will have a "leak" particle effect (as with lava), alerting the player that digging that block will unleash a torrent of water. Glass or any other transparent block is exempt from this.
